Fuel Pressure Calculator
Calculate your vehicle’s fuel pressure requirements with our comprehensive calculator. Determine base pressure, boost pressure, and total fuel pressure for optimal performance.
Step 1: Fuel System Details
Understanding Fuel Pressure
Fuel pressure is critical for proper engine performance. Base pressure is the static fuel pressure, while boost-referenced systems increase fuel pressure with boost to maintain proper fuel delivery under high load conditions.
Step 2: Additional Options
About Fuel Pressure Ratios
The fuel pressure ratio determines how much additional fuel pressure is added per PSI of boost. A 1:1 ratio means fuel pressure increases by 1 PSI for every 1 PSI of boost. This ensures adequate fuel delivery under boost conditions.

Fuel Pressure Breakdown
Fuel Pressure Formula
Total Pressure = Base Pressure + (Boost Pressure × Ratio)
To calculate total fuel pressure, multiply the boost pressure by the fuel pressure ratio and add it to the base fuel pressure. For example: 43 PSI base + (15 PSI boost × 1.0 ratio) = 58 PSI total pressure.
